The water outlet end of the exchanger body 1 is provided with a rear end cover 14, and one side of the rear end cover 14 is provided with a seawater outlet. The front end cover 13 and the rear end cover 14 are respectively arranged at two ends of the sea water cavity 11. Through the arrangement, the fresh water continuously enters the engine to be used as cooling water after being cooled by the fresh water exchanger cooling system, and the sea water can be discharged out of the fresh water exchanger cooling system for external circulation after continuously entering the heat absorption as the cooling water of the fresh water. In short, the fresh water absorbs heat and enters the fresh water cavity 12, and the relatively low-temperature sea water is sucked into the sea water cavity 11 from the outside of the cabin, so that the fresh water in the fresh water cavity 12 is cooled.
In order to achieve the above functions, the seawater chamber 11 is further provided with an exchanger core 3. The exchanger core 3 is a cylindrical core filled in the inner cavity of the seawater cavity 11, the exchanger core 3 comprises a plurality of core tubes, the core tubes are hollow tube bodies, low-temperature seawater enters the front end cover 13 through the seawater inlet and then passes through the exchanger core 3 through the core tubes, the heat of the fresh water is transferred to the seawater in the core tubes through the exchanger core 3, so that the seawater-fresh water heat exchange function is realized, the seawater enters the rear end cover 14 through the seawater outlet after passing through the core tubes, and is discharged into the sea.
Furthermore, the exchanger body 1 is provided with an exhaust pipe 15 inside, and the exhaust pipe 15 is arranged between the seawater chamber 11 and the fresh water chamber 12. When the engine exhaust gas exits the exhaust pipe 15, the seawater in the seawater chamber 11 cools the exhaust pipe 15 so that the engine exhaust gas transfers heat to the seawater through the exhaust pipe wall, thereby reducing the engine heat load.
The seawater pump 2 is arranged on one side of the exchanger body 1, and the seawater pump 2 is connected with the front end cover 13. When the seawater pump 2 is started, the seawater pump 2 pumps seawater into the seawater cavity 11. A seawater inlet pipe 21 is arranged between the seawater pump 2 and the front end cover 13, and the seawater inlet pipe 21 is respectively connected with the water outlet end and the seawater inlet of the seawater pump 2.
In order to achieve the effect of circulating fresh water in the cooling system of the sea-fresh water exchanger, in this embodiment, both sides of the fresh water cavity 12 are respectively provided with a fresh water outlet cover 16 and a fresh water inlet cover 17, one side of the exchanger body 1 is provided with a fresh water pump 4, and both sides of the fresh water pump 4 are respectively connected with the fresh water outlet cover 16 and the fresh water inlet cover 17. A fresh water outlet pipe 41 is arranged between the fresh water pump 4 and the fresh water path outlet cover 16. The fresh water outlet pipe 41 is connected with the fresh water pump 4, so that the fresh water pump 4 can drive the fresh water in the fresh water cavity 12 to enter the fresh water outlet pipe 41 through the fresh water path outlet cover 16 and continue to enter the fresh water pump 4. A fresh water inlet pipe 42 is arranged between the fresh water pump 4 and the fresh water path water inlet cover 17, and the fresh water inlet pipe 42 is connected with the fresh water pump 4, so that the fresh water pump 4 can drive fresh water to enter the fresh water path water inlet cover 17 through the fresh water inlet pipe 42 and continuously enter the fresh water cavity 12, and internal circulation is realized. A thermostat seat 46 is installed on one side of the thermostat cover 44 for installing a thermostat.
In order to control the pressure inside the fresh water chamber 12, a pressure cover 18 is also installed on one side of the fresh water chamber 12.
In a second embodiment, which is implemented on the basis of the first embodiment, the present embodiment provides an engine using a fresh water exchange cooling system, including the fresh water exchange cooling system shown in the first embodiment, where the fresh water exchange cooling system is installed on one side of the engine. The engine comprises a gear chamber cover and a cam shaft, wherein the cam shaft penetrates through one side of the gear chamber cover. In the present embodiment, the seawater pump 2 is mounted on the gear chamber cover, and the seawater pump 2 is connected with the camshaft in a driving manner. When the engine is started, the sea water pump 2 can be driven to operate through the cam shaft without arranging an additional power transmission mechanism, so that the sea water pump 2 is ensured to convey the continuously stable sea water into the sea water cavity 11.
